A metal-nitric oxide electrochemical cell which is fed a gas comprising nitric oxide (NO) and optionally, at least one gas selected from the group consisting of a nitrogen oxide of formula NxOy, oxygen, water vapor, a gaseous hydrocarbon, carbon monoxide and carbon dioxide is provided. The cell may contain a partition which inhibits diffusion of NxOy + active species from the cathode compartment to the anode compartment. Also provided is a rechargeable battery containing the metal- nitric oxide electrochemical cell. A vehicle system wherein NxOy from a combustion engine exhaust is fed to a metal-NxOy battery is additionally provided. |
